Wrongful Termination

person involved was accused of taking a drug from a narcotics cabinet at work in a hospital that leaves a narcotics cabinet open for "anyone" to take anything. When inventory was taken there were 3 types of drugs missing, one of which this person was said to have taken. Maybe there was an accounting error when the drugs were sent from the supplier and entered wrong when resupplied, and the questions can go on and on.... There were supposed to have been 2 people that had seen this person take a drug but there were no security cameras to see who or what happened. There are people that are known to take this particular drug but the person in question was asked to resign or be terminated for "alledgedly" taking it. This person is trustworthy and honest is well liked on her job but since being suspended has heard from none of them. To be terminated would mean losing a TECH-3 certification and a long (8) years seniority job and has no reprimands or warnings against them in that eight years. This person was accused from the outset, with no reason given other than that 2 "credible" witnesses said the person in question did it. Isn't this Defimation of Character? This person has alot to loose along with their good name and I'm sure you can add alot of other things to the list. There was no investigation and this person certainly wasn't given any chance of knowing who their accusers were or given a chance to ask or prove otherwise.
They want to get a lawyer but don't have the funds unless borrowed from a friend, and they want to be able to payback. What would be their chances of sueing for the above reasons?
